Robonaut 2

Hellooooo guys, I was just now looking for so info about new tech and found this article about a new robot made by the NASA and GM,every day every second there's someone who's building something extraordinary and I believe that the robotics it's getting more and more impressive, read the article it's kind of cool :)

Robonaut 2 is expected to be an exemplary co-worker. General Motors and NASA on Thursday introduced Robonaut 2, a humanoid robot being jointly developed at the Johnson Space Center in Houston for use in both the automotive and aerospace industries.

Robonaut 2 is stronger, more dexterous, and more technologically advanced than the original Robonaut, according to NASA. Robonaut, which was developed 10 years ago by NASA and the Defense Advanced Research Project Agency, was intended--as its name implies--for use as a robot astronaut.

Hi guys .. here is some info about how to make a NAS (network-attached-storage)

Make it better, but make it cheaper, too. This seeming contradiction confronts consumer-electronics engineers designing each new generation’s worth of hardware in comparison with its predecessor.


Western Digital’s My Book World Edition NAS device is so named because users can potentially access it from anywhere in the world. Befitting its front-panel illumination scheme, the second-generation iteration is commonly known as the “white-light” model, which follows the initial “blue-ring” version from two years before. This highly integrated design includes only a few chips. The backside (not shown) of the PCB (printed-circuit board) is virtually bare.

1. The heart of the My Book World Edition is Oxford Semiconductor’s OXE810 SOC (system on chip) 2. You waste intra-NAS performance if the network connection is the speed bottleneck. The PLX800 integrated only a 10/100-Mbps Ethernet PHY (physical) layer, so Western Digital bolted an external 1-GbE (gigabit-Ethernet) transceiver to the SOC’s PCI (peripheral-component-interconnect) port. 3. Some reviewers of the first-generation My Book World Edition complained about its low performance, both from a user-interface-response perspective and with respect to its over-network read and write speeds.Western Digital seemingly focused attention on this shortcoming with the second-generation design, whose PLX810 contains an ARM9 core running at 367 MHz versus 200 MHz on the PLX800 used in the first-generation My Book World Edition NAS.
ENJOY haha!
